ULTRASOUND DIAGNOSIS APPARATUS, IMAGE PROCESSING APPARATUS, AND IMAGE PROCESSING METHOD
An ultrasonic diagnostic apparatus according to an embodiment includes an image obtaining unit, a contour position obtaining unit, a volume information calculating unit, and a controlling unit. The image obtaining unit obtains a plurality of groups of two-dimensional ultrasound image data each of which is generated by performing ultrasound scans, the ultrasound scans being performed on each of a plurality of predetermined cross-sectional planes, and performed for predetermined time. The contour position obtaining unit obtains, by performing a tracking process over the predetermined time period, time-series data of contour positions, the contour positions being either one of, or both of, a cavity interior and a cavity exterior of a predetermined site. The volume information calculating unit calculates, on a basis of a plurality of the time-series data of contour positions, volume information of the predetermined site. The controlling unit exercises control so as to output the volume information.

A system includes (a) a catheter for insertion into an organ of a patient, a distal end of the catheter, the distal end including: (i) one or more ultrasound transducers (UT), which are configured to apply ultrasound (US) waves to the organ and to produce one or more US signals indicative of a surface topography of the organ, and (ii) a position sensor, which is configured to produce one or more position signals indicative of one or more respective positions of the distal end inside the organ, and (b) a processor, which is configured, based on the US signals and the position signals, to: (i) produce an anatomical map of the surface topography, and (ii) visualize a change in a slope of the surface topography.
Structures Formed With Sheet Material Configured With At Least One Sound Absorbing Layer
A structure formed with a frame structure and a sheet of material configured to reduce sound is wrapped around or otherwise surrounds the frame structure to form a hammock, basket, meditation pod, animal bed, snore reduction unit, wearable enclosure or other small structure, with an inner, sound limited or reduced volume. The sheet of material includes a base layer and at least one layer of sound-absorbing material, at least one layer of sound barrier material, or both, provided on or integral with the base layer. The sound limited or reduced volume includes an opening that may be closed or partially closed with a flap, canopy or hood. The flap, canopy or hood is preferably made of the same material at the sheet of material surrounding the frame.
Ultrasonic diagnostic apparatus and method for controlling ultrasonic scan using ECG gating
The ultrasonic diagnostic apparatus according to a present embodiment includes processing circuitry. The processing circuitry is configured to: detect, based on an electrocardiogram signal, a specific heart phase in a former heartbeat and a specific heart phase in a latter heartbeat thereafter; sequentially calculate a delay time from the specific heart phase in the latter heartbeat based on a time interval between the specific heart phase in the former heartbeat and the specific heart phase in the latter heartbeat, and control an ultrasonic probe to initiate an ultrasonic scan at a timing when the sequentially calculated delay time is elapsed from the specific heart phase in the latter heartbeat.
Muscle contraction state triggering of quantitative medical diagnostic ultrasound
For quantitative ultrasound imaging with a medical diagnostic ultrasound scanner, muscle tissue is scanned in order to determine the state of contraction. Once the desired state is identified, then QUS imaging is triggered to quantify or measure a tissue property while the muscle is in the desired state. The values of the tissue property at a known state of contraction may be more diagnostically useful or informative. Comparisons of the tissue property across time and/or location may more accurately reflect diagnostic information due to the triggering.
METHOD FOR QUANTIFYING THE ELASTICITY OF A MATERIAL BY ULTRASOUNDS
Method for quantifying the elasticity of a material by ultrasounds, comprising the generation of one acoustic disturbance ultrasound beam (10) for the first excitation point (1), for generating a shear wave (11), a measurement of the shear wave (11) at a plurality of lines of sight placed in a region of interest (2) at different predetermined distances from the first excitation point (1), the calculation of the speed of the measured shear wave (11) and the assessment, by calculation, of a mean stiffness value of the material in the region of interest (2) on the basis of the measured speed of the shear wave (11). In the acquired image (3) a second excitation point (4) is defined, in such a position that the region of interest (2) is interposed between the first excitation point (1) and the second excitation point (4). The method for the second excitation point (4) is carried out, for calculating the speed of the shear wave (11) for the second excitation point (4), and the assessment by calculation of the mean stiffness value is carried out on the basis of the average between the speed of the shear wave measured for the first excitation point (1) and the speed of the shear wave measured for the second excitation point (4).
APPARATUS FOR VISUALIZING TISSUE PROPERTY
The present invention relates to an apparatus (1) comprising a signal processor (2) for processing measurement signals (3) from a motion-mode ultrasound measurement and a rendering device (4) coupled to a processor (2) for rendering a one-dimensional representation (40) along a temporal axis (41) indicative of a property within a tissue. The values (42) in the one-dimensional representation (40) are derived on the basis of measured values in an observation window (12, 22, 32) defined on an M-mode ultrasound image (10), a tissue velocity image (20) or a strain rate image (30).
IMAGE ANALYSIS FOR SCORING MOTION OF A HEART WALL
The present disclosure relates to a system (100) for scoring motion of a heart wall (214, 218). The system (100) includes an imaging system (102) operable to acquire a first image (230) of the heart wall (214, 218) at a first time and a second image (240) of the heart wall (214, 218) at a second time. A processor (108) is provided to identify a first set of contour data in the first image (230); and a second set of contour data in the second image (240). The processor (108) defines at least one element (E.sub.i) representing a cardiac cyclic change in a section of the heart wall (214, 218) in dependence on the first and second sets of contour data. Each element (E.sub.i) is analysed to generate at least one metric which is compared with a reference data model to score the motion of the corresponding section of the heart wall (214, 218). The disclosure also relates to a method of scoring motion of a heart wall (214, 218); and a non-transitory computer-readable medium.

An ultrasound scanning apparatus comprises an ultrasound scanning unit, an ultrasound controller for controlling the operation of the ultrasound scanning unit, detecting the operation state of the ultrasound scanning unit, generating a first enable signal when detecting that the operation state of the ultrasound scanning unit is transferred from an operating state to a non-operating state and generating a second enable signal when detecting that the operation state of the ultrasound scanning unit is transferred from the non-operating state to the operating state, and an enable output end for transmitting the first enable signal or the second enable signal to the breathing machine to control the running of the breathing machine.
SYSTEMS AND METHODS FOR MANAGING A PATIENT
Implementations described and claimed herein provide systems and methods for managing one or more patients. In one implementation, an imaging window is determined based on a location of a probe. A primary image cross-section for the imaging window is identified for the imaging window. At least one image is generated along the primary image cross-section using patient data captured using the probe. The at least one image is compared to an expected image contour scaffold of the primary image cross-section. The probe is commanded to fine-tune an imaging plane based on the comparison until the at least one image matches the expected image contour scaffold of the primary image cross-section.
